Covering up with a t-shirt may seem like complete sun protection. But did you know you're not really shielding yourself from the sun's damaging UV rays? The average white cotton t-shirt offers just UPF 5 protection - a level that dermatologists would find inadequate.

Enter RIT Sun Guard UPF 30 Fabric Treatment: an easy-to-use laundry treatment powder that washes UV protection right into clothes. Sun Guard boosts the UPF protection of a white cotton t-shirt from just UPF 5 to UPF 30, blocking more than 95% of the sun's harmful UVA and UVB rays. All you need to do is add one package of Sun Guard to a load of laundry and UV protection will be washed right into your clothes, lasting up to 20 washings.

Amazing for school uniforms, outdoor trades, landscapers, sports gear, exercise clothing and more.

This package contains 454g (1lb) of RIT Sun Guard powder with handy dosing scoop. Also available in single use 28.4g box in our store.
